VLT ® 2000 Series Description of parameters I 008 Local reversing (LOCAL/FWD/REV) Value: ✭ Disable (DISABLE) [0] Enable (ENABLE) [1] 004 Local reference (LOCAL SPEED) Value: 0-f MAX I Function: You choose Local reference if you want to set the speed (frequency) via the control panel. I 009 Local jog (LOCAL JOG) Value: Disable (DISABLE) [0] ✭ Enable (ENABLE) [1] Description: To use this parameter you must choose Local with external stop or Local and remote in parameter 003. The output frequency of the frequency converter can be changed by means of the “+” and “ − ” keys. If the mains supply is disconnected the value changes to 0.00.
Parameter 004 cannot be controlled via the serial bus, RS 232. There is no automatic switch back to Parameter group from this parameter. In parameter 010 you can lock data changes in parameter 004. I 010 Local reference (LOC REFERENCE) Value: Disable (DISABLE) [0] ✭ Enable (ENABLE) [1] Enable and save (ENABLE AND SAVE) [2] Function: You can enable/disable the function via the control panel. Furthermore you can choose whether it must be possible to change the output frequency via para- meter 004. I 005 Display value (VALUE AT MAX.) Value: 1 - 9999 ✭ 1000 Description: If you choose Disable in parameter 006, 007, 008 or 009 you cannot activate the function via the control panel.
If you choose Disable in parameter 010 the output frequency cannot be changed via parameter 004. You can prevent data change by setting parameter 013 to Locked . If you choose Enable and save a change of local speed reference will be saved automatically after 15 sec. Function: You can choose to have the speed/frequency displayed without the unit Hz behind the value. Description: The value will only be read out if Display is selected in Display group. It is not possible to change Hz to another unit. I I 006 Local reset (LOCAL RESET) Value: Disable (DISABLE) [0] ✭ Enable (ENABLE) [1] 013 Data change lock (DATA CHC. LOCK) Value:
✭ Not locked (NOT LOCKED) [0] Locked (LOCKED) [1] I 007 Local start / stop (LOC START/STOP) Value: Disable (DISABLE) [0] ✭ Enable (ENABLE) [1] Function: There is a way to avoid unintended programming. Description: If you choose Locked you cannot make any data change in any parameter. However, it is still possible to change the local reference. If data change is attempted with data change lock, the display shows: DATA LOCKED. ✭ = Factory setting. Text in ( ) = Display text. The figures in [ ] are used in bus communication. 62 MG.20.B6.02 – VLT is a registered Danfoss trademark
